Question 2
Type: MCSA
A client is receiving
100 mL of intravenous fluid for 18 hours. How many liters of fluid did the
client receive?
1.
1.2
2.
1.5
3.
1.8
4.
2.2
Correct Answer: 3
Rationale 1: L = 1
L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 =
1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 =
1.8. The mL and the hrs cancel each other out, which leaves the label of
the answer as L. The client received 1.8 L of intravenous fluid.
Rationale 2: L = 1
L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 =
1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 =
1.8. The mL and the hrs cancel each other out, which leaves the label of
the answer as L. The client received 1.8 L of intravenous fluid.
Rationale 3: L = 1 L/1000
mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 = 1800).
Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 = 1.8. The
mL and the hrs cancel each other out, which leaves the label of the answer as
L. The client received 1.8 L of intravenous fluid.
Rationale 4: L = 1
L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x 100 x 18 =
1800). Multiply all the denomenators (1000 x 1 x 1 = 1000). 1800/1000 =
1.8. The mL and the hrs cancel each other out, which leaves the label of
the answer as L. The client received 1.8 L of intravenous fluid.
Global Rationale:
L = 1 L/1000 mL x 100 mL/1 hr x 18 hr/1. Multiply all the numerators (1 x
100 x 18 = 1800). Multiply all the denomenators (1000 x 1 x 1 = 1000).
1800/1000 = 1.8. The mL and the hrs cancel each other out, which leaves
the label of the answer as L. The client received 1.8 L of intravenous
fluid.

suspension every 6 hours. How many T of the medication will the client take in
1 day?
1.
2
2.
2 1/3
3.
2 2/3
4.
3 1/3
Correct Answer: 3
Rationale 1: T/day = 1
T/3 tsp x 2 tsp/6 hrs x 24 hrs/1 day. Multiply all the numerators (1 x 2
x 24 = 48). Multiply all the denominators (3 x 6 x 1 = 18). 48/18 = 2.66.
Household measurements use fractions, not decimals. Convert 0.66 into a
fraction by placing 66/100 which reduces to 2/3; therefore, the answer is
2 2/3 T will be taken each day.
Rationale 2: T/day = 1
T/3 tsp x 2 tsp/6 hrs x 24 hrs/1 day. Multiply all the numerators (1 x 2
x 24 = 48). Multiply all the denominators (3 x 6 x 1 = 18). 48/18 = 2.66.

2. 5
3. 0.5
4. 0.05
Correct Answer: 3
Rationale 1: mg = 1
mg/ 1,000 mcg x 500 mcg/1. Multiply the numerators (1 x 500 = 500).
Multiply the denominators (1,000 x 1 = 1,000). 500/1000 = 0.5.
Rationale 2: mg = 1

medication. How many doses of medication will the client have within one
bottle?
1. 4
2. 8
3. 16
4. 32
Correct Answer: 2
Rationale 1: doses per
bottle= 1 dose/ 4 T x 2 T/ 1 ounce x 16 ounces/1 bottle. Multiply the
numerators (1 x 2 x 16 = 32). Multiply the denominators (4 x 1 x 1 = 4).
32/4 = 8 doses per 1 bottle.
Rationale 2: doses per
bottle= 1 dose/ 4 T x 2 T/ 1 ounce x 16 ounces/1 bottle. Multiply the
numerators (1 x 2 x 16 = 32). Multiply the denominators (4 x 1 x 1 = 4).
32/4 = 8 doses per 1 bottle.

3. 40
4. 400
Correct Answer: 4
Rationale 1: g = 1,000
g/1 kg x 0.4 kg/ 1. Multiply the numerators (1,000 x 0.4 = 400). Multiply the
denominators (1 x 1= 1). 400/1= 400 g.
Rationale 2: g = 1,000
g/1 kg x 0.4 kg/ 1. Multiply the numerators (1,000 x 0.4 = 400). Multiply the

many milligrams of the medication will the client receive for each dose?
1. 0.5 milligrams
2. 5 milligrams
3. 50 milligrams
4. 500 milligrams
Correct Answer: 4
Rationale 1: mg/dose =
1000 mg/ 1 g x 2 g/24 hrs x 6 hrs/1 dose. Multiply the numerators (1000 x 2 x 6
= 12,000). Multiply the denominators (1 x 24 x 1 = 24). 12,000/24 = 500
mg/dose.
Rationale 2: mg/dose =
1000 mg/ 1 g x 2 g/24 hrs x 6 hrs/1 dose. Multiply the numerators (1000 x 2 x 6
= 12,000). Multiply the denominators (1 x 24 x 1 = 24). 12,000/24 = 500
mg/dose.
Rationale 3: mg/dose =
1000 mg/ 1 g x 2 g/24 hrs x 6 hrs/1 dose. Multiply the numerators (1000 x 2 x 6
= 12,000). Multiply the denominators (1 x 24 x 1 = 24). 12,000/24 = 500
mg/dose.
Rationale 4: mg/dose =
1000 mg/ 1 g x 2 g/24 hrs x 6 hrs/1 dose. Multiply the numerators (1000 x 2 x 6
= 12,000). Multiply the denominators (1 x 24 x 1 = 24). 12,000/24 = 500
mg/dose.
Global Rationale:
mg/dose = 1000 mg/ 1 g x 2 g/24 hrs x 6 hrs/1 dose. Multiply the
numerators (1000 x 2 x 6 = 12,000). Multiply the denominators (1 x 24 x 1 =

Question 15
Type: MCSA
A client’s nasogastric
tube was inserted 56 centimeters and was taped to the nose. Currently the tape
marking is 40 millimeters from the nose. How many centimeters of the
nasogastric tube remains in the client?
1. 16
2. 28
3. 42
4. 52
Correct Answer: 4
Rationale 1: cm = 1
cm/10 mm x 40 mm/1. Multiply the numerators (1 x 40 = 40). Multiply
the denominators (10 x 1 = 10). 40/10 = 4 cm. 56 cm – 4 cm = 52
centimeters remains in the client.
Rationale 2: cm = 1
cm/10 mm x 40 mm/1. Multiply the numerators (1 x 40 = 40). Multiply
the denominators (10 x 1 = 10). 40/10 = 4 cm. 56 cm – 4 cm = 52 centimeters
remains in the client.
Rationale 3: cm = 1
cm/10 mm x 40 mm/1. Multiply the numerators (1 x 40 = 40). Multiply
the denominators (10 x 1 = 10). 40/10 = 4 cm. 56 cm – 4 cm = 52
centimeters remains in the client.
Rationale 4: cm = 1
cm/10 mm x 40 mm/1. Multiply the numerators (1 x 40 = 40). Multiply
the denominators (10 x 1 = 10). 40/10 = 4 cm. 56 cm – 4 cm = 52
centimeters remains in the client.
Global Rationale: cm =
1 cm/10 mm x 40 mm/1. Multiply the numerators (1 x 40 = 40). Multiply
the denominators (10 x 1 = 10). 40/10 = 4 cm. 56 cm – 4 cm = 52
centimeters remains in the client.

A client diagnosed
with multiple sclerosis (MS) is prescribed 30 mcg of interferon beta – 1a by
injection once a week. How many milligrams of Avonex will the patient receive
in one week?
1. 30 mg
2. 3 mg
3. 0.3 mg
4. 0.03 mg
Correct Answer: 4
Rationale 1: mg/week =
1 mg/1000 mcg x 30 mcg/ week. Multiply the numerators (1 x 30 = 30).
Multiply the denominators (1000 x 1 = 1000). 30/1000 = 0.03 mg
Rationale 2: mg/week =
1 mg/1000 mcg x 30 mcg/ week. Multiply the numerators (1 x 30 = 30).
Multiply the denominators (1000 x 1 = 1000). 30/1000 = 0.03 mg
Rationale 3: mg/week =
1 mg/1000 mcg x 30 mcg/ week. Multiply the numerators (1 x 30 = 30).
Multiply the denominators (1000 x 1 = 1000). 30/1000 = 0.03 mg
Rationale 4: mg/week =
1 mg/1000 mcg x 30 mcg/ week. Multiply the numerators (1 x 30 = 30).
Multiply the denominators (1000 x 1 = 1000). 30/1000 = 0.03 mg
Global Rationale:
mg/week = 1 mg/1000 mcg x 30 mcg/ week. Multiply the numerators (1 x 30 =
30). Multiply the denominators (1000 x 1 = 1000). 30/1000 = 0.03 mg

month. How many grams of medication will the client receive in 3 months?
1. 90 g
2. 9 g
3. 0.9 g
4. 0.09 g
Correct Answer: 3
Rationale 1: g/3
months = 1 g/1000 mg x 300 mg/1 month x 3 months/1. Multiply the
numerators (1 x 300 x 3 = 900). Multiply the numerators (1000 x 1 x 1 =
1000). 900/1000 = 0.9 g/3 months.
Rationale 2: g/3
months = 1 g/1000 mg x 300 mg/1 month x 3 months/1. Multiply the
numerators (1 x 300 x 3 = 900). Multiply the numerators (1000 x 1 x 1 = 1000).
900/1000 = 0.9 g/3 months.
Rationale 3: g/3
months = 1 g/1000 mg x 300 mg/1 month x 3 months/1. Multiply the
numerators (1 x 300 x 3 = 900). Multiply the numerators (1000 x 1 x 1 =

Question 18
Type: MCSA
The client is
prescribed propantheline bromide 30 mg PO ac and hs. How many grams will
the client receive in a one week period?
1. 42 g
2. 4.2 g
3. 0.42 g
4. 0.042 g
Correct Answer: 3
Rationale 1: g/week =
1 g/1000 mg x 30 mg/dose x 2 doses/day x 7 days/1 week. Multiply the numerators
(1 x 30 x 2 x 7 = 420). Multiply the denominators (1000 x 1 x 1 x 1 = 1000).
420/1000 = 0.42 g/week.
Rationale 2: g/week =
1 g/1000 mg x 30 mg/dose x 2 doses/day x 7 days/1 week. Multiply the numerators
(1 x 30 x 2 x 7 = 420). Multiply the denominators (1000 x 1 x 1 x 1 = 1000).
420/1000 = 0.42 g/week.
Rationale 3: g/week =
1 g/1000 mg x 30 mg/dose x 2 doses/day x 7 days/1 week. Multiply the numerators
(1 x 30 x 2 x 7 = 420). Multiply the denominators (1000 x 1 x 1 x 1 = 1000).
420/1000 = 0.42 g/week.
Rationale 4: g/week =
1 g/1000 mg x 30 mg/dose x 2 doses/day x 7 days/1 week. Multiply the numerators
(1 x 30 x 2 x 7 = 420). Multiply the denominators (1000 x 1 x 1 x 1 = 1000).
420/1000 = 0.42 g/week.
Global Rationale:
g/week = 1 g/1000 mg x 30 mg/dose x 2 doses/day x 7 days/1 week. Multiply the
numerators (1 x 30 x 2 x 7 = 420). Multiply the denominators (1000 x 1 x 1 x 1
